Allow for Overrides of API Versions

[knechtionscoding]

When invoking Helm via kustomize or other tools it is possible that the API server isn't available to respond to a capabilities request. In these cases we should allow engineers to override the capabilities via the values.yaml.

https://github.com/fluent/helm-charts/blob/main/charts/fluent-bit/templates/_helpers.tpl#L69 example of a location where this is needed. Should just add the to the initial if condition to support a values.yaml declaration.

https://github.com/renovatebot/helm-charts/blob/main/charts/renovate/templates/cronjob.yaml#L1-L9 is an example implementation from a different helm chart.
